# Finding Coordinates of a Slope

#### larry21

A lines passes through the point (1,-3). State the coordinates of one other point on the line so that the slope of the lines is:

a. 4
b. undefined
c. (3/4)

Hi larry21,

[a] slope = 4, points (1, -3) and (x, y)

$$\displaystyle \frac{y_2-y_1}{x_2-x_1}=4$$

$$\displaystyle \frac{y- ^-3}{x-1}=\frac{4}{1}$$

$$\displaystyle y+3=4 \:\: and \:\: x-1=1$$

$$\displaystyle y=1 \:\:and\:\:x=2$$

$$\displaystyle (2, 1)$$

Do you think you could follow these steps and complete
the others?

If the slope is "undefined" how would I solve it?

Edit: Never mind, figured it out.
